Application filed May 6, 1916. Serial No. 95,848

To all whom it may concern:

Be it known that I, JOHN F. SULLENBER- GER, a citizen of the UnitedStates, residing at Columbus, in the county of Muscogee and State ofGeorgia, have invented new and useful Improvements in Drying-Machines,of which the following is a specification.

The invention relates to dryingmachines, and more particularly to theclass of rotary drying machines for grain or minute substances ormaterials.

The primary object of the invention is the provision of a machine ofthis character wherein the drying pans or sections are stacked andreadily interchangeable so that of Flg. 1;

any one section or pan will fit upon another and in event thatthecapacity of the machine is to be varied for increasing or decreasingthe capacity the sections or pans can be added to 'or discarded.

Another object of the invention is the provision of a machine of thischaracter wherein hominy, grits,'meal, grain and various materials canbe thoroughly dried therein, the drying sections or pans being heatedfrom coils through which circulates steam, and said sections or pansbeing incased so as to retain the heat therein for the thorough dryingof the materials after the introduction thereof at the. head or top ofthe machine, which dried material is discharged from the bottom of saidmachine.

A further object of the invention is the provision of a machine of thischaracter wherein the construction thereof is novel in form and thecarriers or feeders for the materials are also novel in formv so thatthe trend of the material will be in zigzag fashion from the top to thebottom of the machine so that the thorough drying of the Specificationof Letters Patent.

after described, and the scope of the application of which will beindicated in the appended claims. 4 a

In the accompanying drawings:

Figure 1 is a side elevation of a machine constructed in accordance withthe invention;

Fig. 2 is a top plan view thereof;

Fig. 3 is a fragmentary vertical sectional elevation taken. through theupper portion of the machine;

Fig. 1 is a view similar to Fig. 3, taken through the lower portion ofthe machine;

F ig.. 5 is a sectional view on the line 5-5 of Fig. 1;

Fig. 6 is a sectional view on the line 6-6 Fig. 7 is a bottom plan viewof the machine;

Fig. 8 is a plan view of one of the rotary agitator carriers or feeders;

Fig.9 is a plan view of one of the pans.

Similar reference characters indicate corresponding parts throughout theseveral I views of the drawings.

' Referring to the drawings in detail, A designates a casing preferablymade in section and from sheet metal, the sections of which aredetachably fastened together in any suitable manner, and within thiscase is arranged the machine, which comprises a plurality of superposed,annular rings 10, each being formed with outer peripheral flanges 11through which are passed at intervals bolts 12, the same being alsopassed through spacer sleeves 13 arranged between the flanges and therings adjacent each other, and in this manner the rings are united inseries. Each ring 10 has at its lowermost edge an internal annularsupporting flange 14 upon which rests a drying pan or section 15 adaptedto be riveted or otherwise secured to the flange, and upon the underface of the pan or section 15 are bridge straps 16 which supportdirectly beneath the said pan or section a steam coil 17 it beingunderstood,

of course, that the coils are arranged in series correspondinglyto theseries of pans or sections 15 and are connected together so that steamentering one of the coils will circulate through the said coils of theseries, the steam being supplied thereto from any suitable source, andthe condensation is delivered to the boiler or other steam generatorconstituting the supply for the live steam to the coil.

Extending centrally through the pans or sections 15 is a vertical shaft18, the lower end of which is journaled in a boxing or bearing 19 fittedwithin a supporting spider 20 formed with base feet 21, and this spideris connected to the series of rings through the medium of the base ring22, as shown,

while at the top of the series of rings is a head 23 formed with acenter bearing 24 for the shaft 18, which latter hasfitted on its upperend a beveled gear 25 meshing witlfa pinion 26 fixed to one end vof adrive shaft 27 journal-ed in bearings 28 supported by the'head 23, theshaft 27 being driven in any suitable manner.

. wardly to the periphery of the machine, and

the coils circulating the steam heat the pan or sections 15 for thedrying of the material during its zigzag course from the top of themachine to the bottom thereof.

The pans or sections 15 alternately are formed with peripheral andcentral discharge apertures 31 and 32 respectively, so that the materialwill be discharged from one pan at the periphery thereof and from'another pan at the center thereof, thereby taking a zigzag course by theaction of the series of spirals 29 and 30 thereon from the top of themachine to the bottom thereof so that the material will be thoroughlydried before it is delivered from said machineat the bottom thereof. Thecase A serves to retain the heat within the machine and the top or head23 is formed with diametrically opposed openings 88 which permit theescape of moisture from the material and also permit the introduction ofthe material on to the uppermost pan 1:") within the machine fromhoppers or other containers, while the material at the bottom of themachine is discharged therefrom into a chute or other conveyer throughthe delivery aperture 34: in the lowermost pan or section 15 of theseries.

On each spiral 29 and 30 are fixed angularly disposed wings or blades 35which serve as agitators for the material acted upon by the spirals.Each spiral 29 and 30 is formed with a spider brace 86, which materiallystrengthens the same and the hub of each spiral '37 is fastened to theshaft 18 through the medium of a set screw 38 which is threaded in thehub.

From the foregoing description, taken in connection 'with theaccompanying drawings, the construction and operation of the hereindescribed drying machine w1ll be readily apparent and, therefore, a moreexflanges and spacers together, pans support ed upon the internalflanges in the respective rings and having openings centrally andperipherally in alternate relation, means heneath each pan for heatingthe same, and feeders arranged to travel over the pan for advancingmaterials to the openings therein.
